Irwin 33/64" x 6" Silver & Deming Drill Bit (91133)

The Irwin 33/64" x 6" Silver & Deming Drill Bit (91133) is a robust and reliable tool engineered for heavy-duty drilling applications. As part of the respected Irwin 911/901 series, this bit is designed to provide consistent performance in a variety of materials, including metals, wood, and plastics. Its construction from premium high-speed steel ensures durability and strength, while the black oxide coating offers protection against corrosion. The unique Silver & Deming design incorporates a 1/2" reduced shank with three flats, which is specifically engineered to provide a secure, non-slip grip in any standard 1/2" drill chuck, whether in a portable drill or a stationary drill press. The bit’s 118° chisel point is a standard, effective design for general-purpose drilling, making it a versatile addition to any professional’s toolkit, especially for tasks in automotive, body shop, and metal fabrication environments.

KEY FEATURES AND BENEFITS:

• Corrosion Resistance: The black oxide coating on the high-speed steel body provides a protective layer that helps prevent rust and corrosion, extending the bit’s lifespan and maintaining its cutting performance over time.
• Enhanced Grip and Stability: The 1/2" reduced shank features a unique three-flat design, which securely locks into a drill chuck. This design significantly reduces the chance of the bit slipping or spinning during high-torque applications, leading to safer and more precise drilling.
• Versatile Drilling Performance: The 118° chisel point is a general-purpose tip that is effective across a wide range of materials, including various metals, woods, and plastics, making this a highly adaptable tool for different job requirements.
• Optimized for Heavy-Duty Use: Constructed from high-speed steel, this drill bit is built to withstand the demands of heavy-duty metal drilling, making it an excellent choice for professional applications in automotive, body shop, and fabrication settings.

SPECIFICATIONS:

• Drill Bit Size: 33/64"
• Overall Length: 6"
• Shank Diameter: 1/2"
• Shank Type: Reduced with 3 flats
• Point Angle: 118°
• Material: High-Speed Steel (HSS)
• Coating: Black Oxide
• Series: 911/901

HOW TO USE:

1. Select the Right Tool: Ensure you are using a drill with a 1/2" chuck capacity, such as a portable power drill or a drill press.
2. Secure the Bit: Loosen the chuck jaws and insert the 1/2" reduced shank of the drill bit. Tighten the chuck firmly, ensuring that the three flat sides of the shank are securely gripped by the jaws to prevent slippage.
3. Prepare the Material: Mark the desired drilling location on your workpiece. For metal, you may use a center punch to create a small indentation, which will help guide the bit and prevent it from wandering.
4. Set the Drill Speed: Adjust the drill to the appropriate speed setting for your material. Slower speeds are generally recommended for harder metals to prevent overheating, while faster speeds can be used for softer materials.
5. Begin Drilling: Apply steady, even pressure and begin drilling. Allow the bit to cut without forcing it. Pull the bit out periodically to clear chips and debris from the hole, especially when drilling deep holes.
